  • Shotdetect : compiling error ("undefined reference")

    8 juillet 2015, par Voprosnik

    I am using Cygwin and I trying to install the program Shotdetect. I downloaded the source with git and also downloaded, compiled and installed ffmpeg through git.

    Installation of shotdetect doesn’t follow the ./configure && make && make install routine, but a cmake system of which I have no experience. Nonetheless there is a script that automates compiling and installation.

    Near the final stages of the compiling, I get a long series of errors concerning some ffmpeg modules :

    Searching online for similar errors, I found the following proposed solutions

    1) fix pkg-config setup so configure will find out all dependencies ;

    2) build ffmpeg (libavcodec) without external dependencies ;

    3) add external dependencies manually with configure —extra-ldflags

    I guess the problem lies on how i compiled ffmpeg (just configure with no options) but other than that have no idea what to do with either of the above suggestions. Should I recompile ffmpeg with different options ?

  • Destreamer (FFMPEG / Youtube-DL) - Can't download video, Invalid DTS, Invalid timestamps message

    1er avril 2020, par toprun91

    I'm using Destreamer a program that essentially lets you download microsoft stream videos by passing a key URL with a cookie down to Youtube-dl which then calls into ffmpeg.

    



    Whenever I try to download a video using this program I get tons of repeating lines of text (errors ?) like this :

    This continues to fill the screen and scroll with the same type of lines of text and then after a couple of hours it does eventually download the video but without sound.

    



    I am trying to work out why this is happening and why the video downloads without sound.

    



    Some key information :

    



      

    • I am using windows + powershell but also experience the same thing on
Linux (Kubuntu)

      • 


    • I am using the latest versions of FFMPEG, youtube-dl node.js

      • 


    • The program (destreamer) brings up a chromium window to authenticate.
In the Chromium window the video doesn't actually play properly and
gives Error code 0x20400003 The video plays fine in all other
browsers I have including Edge, Chrome, and Firefox

      • 


    



    Thanks for your help !

    


  • ffmpeg for android, out of memory on encoding h264

    15 juin 2018, par Rafael Lima

    I’m getting an weird error when enconding a video with ffmpeg on android

    Failed to inject frame into filter network: Out of memory

    Althoug is a pretty objective error, I do believe this is some "generic message" for another problem, because the video I used for testing is 17MB and less than 11 seconds length and I’ve sucessfully tested with videos bigger than 200MB and longer than 5min

    This problem happens to any video vertical videos recorded on my phone (the videos were recorded and play fine on my phone but i cant reencode them... other video h264 were encoded fine on same phone)

    this is ffmpeg output

    =====================UPDATE===================

    I re-run the command with -v 9 -loglevel 99 and got paste the log file at :

    https://pastebin.com/ihawsPvZ

    If someone have real good expertise at ffmpeg i would apreciate very much the help

    =====================UPDATE 2=================

    I made more tests and the problem happens only when i record the video with my phone at vertical (other videos in vertical work and videos from my phone in horizontal also work)

    ==================UPDATE 3====================
    I detected the problem happens to ANY video with the

    Metadata:
    
      rotate          : 90 (or any value)

    It was suggested to use -noautorotate as workaround and it WORKDED, but this implies in tons of other complications ex :

    -if i decide to apply any filter to the video, it will be applied to the horizontal version but the video will be played at vertical producing a totally different effect

    ex : https://i.stack.imgur.com/R3jXJ.jpg (at this photo the drawtext filter should be placed at bottom line with horizontal text, but as ffmpeg can’t handle the orientation it is missplaced and rotated at runtime producing this vertical message)

    -I checked and if I set -metadata:s:v:0 rotate= while enconding it has no effect ex :

    ffmpeg -i input.mp4 -c copy -metadata:s:v:0 rotate= output.mp4
    will remove the rotate metadata and produce a non rotated video

    BUT
    ffmpeg -i input.mp4 -c:v libx264 -metadata:s:v:0 rotate= output.mp4
    will keep the metadata and the produced video will be played rotated (this behavior was also noticed on the official ffmpeg 4.0 binaries for windows available at ffmpeg website)

    I’M STILL LOOKING FOR A BETTER SOLUTION, THANKS FOR THE HELP
